Prerequisites for recovering the NetBackup catalog or NetBackup catalog image files
Caution:
NetBackup Catalog Recovery is a critical process. During the catalog recovery process, you must not perform any other operation using the NetBackup web UI or the NetBackup Administration Console. The NetBackup database and all the services will be down during the process.
Caution:
Do not run any client backups before you recover the NetBackup catalog or catalog image files.
Note:
After a catalog recovery, NetBackup freezes the removeable media that contains the catalog backup. This operation prevents a subsequent accidental overwrite action on the final catalog backup image on the media. This final image pertains to the actual catalog backup itself, and its recovery is not part of the catalog recovery. You can unfreeze the media.
Before you recover the NetBackup catalog or NetBackup catalog image files, review the following requirements and information:
Ensure that NetBackup is running in the recovery environment.
Configure the recovery devices in NetBackup.
Ensure that the media on which the catalog backups exist are available to NetBackup.
If the NetBackup primary server is part of a cluster, ensure that the cluster is functional.
You must be logged on to the primary server from which you want to recover the catalog.
If NetBackup is configured as a highly available application (cluster or global cluster), freeze the cluster before you begin the recovery process to prevent a failover. Then, unfreeze the cluster after the recovery process is complete.
To recover the catalog from the web UI, you must have the Administrator role or similar permissions. To use the bprecover command, you must have root (administrative) privileges.
If the catalog was backed up on a NAT media server, you must carry out certain steps to establish a connection with the NAT media server before catalog recovery.
See Establishing a connection with NAT media server before catalog recovery.
Ensure that you have the location of the disaster recovery file.
Recovery of the entire catalog or the catalog image files relies on the disaster recovery information. This file contains the NetBackup primary server host identity. The location of the disaster recovery file is configured in the catalog backup policy and is saved in a file during the catalog backup.
See NetBackup disaster recovery email example.
If you do not have the disaster recovery file, you can still recover the catalog. However, the process is much more difficult and time-consuming.
See Recovering the NetBackup catalog without the disaster recovery file.
